.This invention relates to a farming implement, and its primary object is the provision of a farming implement for use in the process of sub-surface tillage and fertilization, which implement replaces sod previously stood on edge by a previous plowing operation.

Another object of the invention resides in a farming implement having a soil engaging member adapted to engage the furrow between the sod rows to move the sod in a direction opposite that which it assumes after being stood on end and to repla-ce such sod to substantially original position before being stood on end.

Still another object of the invention resides in a farming implement having a forward edge inclining a certain distance beyond a vertical line at the front thereof, with the main body portion inclining at a substantial angle on the opposite side of the vertical line, whereby to replace sod stood on edge to substantiallyits original position prior to being stood on end.

Another object of the invention consists in the method of cultivating soil by the replacing of sod which has been previously stood on edge by a prior plowing operation so as to bring back the sod to substantially its former original position.

Numerous other objects and advantages will be apparent throughout the progress of the following specication.

The accompanying drawings illustrate a selected `embodiment of the invention and the views therein are as follows:

Fig. 1 is a detail top plan view of the improved farming implement;

Fig. 2 is a detail side elevational view thereof;

Fig. 3 is a detail sectional View on the line 3 3 of Fig. 1;

Fig. 4 is a detail sectional view on the line 4-4 of Fig. 1, showing the contour of the blade and position of the sod at the forward end of the body member; and

Figs. 5, 6, and 7 are detail views taken on the lines 5, 6 6, and 1 1, respectively of Fig. 1 showing the contour of the blade and the respective positions of the sod, and showing the manner in which the soil is progressively returned to its substantially normal position prior to the plowing operation which has stood the sod on end.

The particular implement herein shown for the purpose of illustrating the invention comprises a body member or frame I having spaced side bars 2, 2 to which supporting elements 3 are connected, as indicated at 4. The forward end of the frame I may be supported for traction by wheels 5 mounted on a transverse axle 6. An attaching member 'I is operatively secured to the framework whereby the implement may be attachedA to a tractor or other pulling means for moving the implement along the ground. y The rear end of the frame or support l may be connected to a roller 8 mounted on any axle 9 suitably housed in bearings I0 secured to the side bars 2. An attaching plate II may be secured between the opposed inner faces I2 of the supporting members 3. This attaching plate II is secured, as indicated at I3, to the body member I4 of the implement.

The body member I4, in the form of a continuous plate, is provided with an extreme front end I5 which extends in a vertical direction but which inclines a certain distance beyond a vertical line, to the right as shown in Figs. 3 and 4. The rbody from front to rear inclines progressively from a point on one side of a vertical line at the front to a point on the other side of the vertical line, as shown in Figs. 3, 5, 6, and '7. The body I4 also slopes Vor inclines upwardly from its front.

nose portion I6 to its maximum point of vertical inclination, as indicated at I1, Fig. 2, Where it slopes downwardly toits extreme rear end I8. The body I4, therefore, is inclined longitudinally and inclines transversely a certain distance on one side of a vertical line progressively toward the rear where it inclines at a steep angle at the rear end of the body. .The bottom edge or sole I9 of the body i4 is adapted to engage the bottom of a furrow 20 which has been previously created by means of a former plowing operation which has stood the sod 2I on edge, as shown in Fig. 4.

'Ihe implement when Ibeing propelled will have its nose I6 inclined on one side of a vertical center line, as indicated at 22 in Fig. 4, whereupon it will iit between the various rows of stood-onedge sod. The movement of the implement will then cause a row of stood-on-edge sod to be engaged by the acting surface 23 of the body I4, whereupon the sod will become engaged with a part of the surface 23 of the body I4 at a point where the progressive arcuate inclination of the body, as indicated at 24, Fig. 5, will turn the vsod from the position shown in Fig. 4 to the position shown in Fig. 5. The sod is then acted upon progressively by the surface 23 of the body until it contacts with the surface 23 of the body I4 which is of still greater arcuate angularity, asindicated at 25 in Fig. 6. At or toward the end of the body I4 the surface 23 will be at its greatest an soil is re-laid to substantially its original position.` The farming implement herein disclosed is"l adapted to co-operate with a conventional plowfor returning sod to its substantially original position after the sod has been turned over* orstood* on end by a previous plowing operation."'1h`e" present implement is adapted; iorg'use irrfseriiesr with a plow which precedes it, and may `be attached to the plow or it may be placed behind' the plow and propelled by Athe same mover which translates the plow.
